Audit 9.4 (t4:419): "Lunes, 3 de agosto" now renders between the
schedule pill and the hero time -- purely additive, a new sibling
Text touching neither element. New formato_fechas.dart helper
fechaLargaConDiaSemana (locale-aware via DateFormat.MMMMEEEEd).
Audit 9.10 (t4:433): the highlighted snooze tile gains a "usual"
qualifier (new ARB key alarmSnoozeUsualLabel) alongside the original
flat label -- resolved DIFFERENTLY than its sibling 9.9 (permanently
rejected, id 2525): instead of splitting the flat
alarmSnoozeOptionLabel string into two differently-sized Text nodes
(which would make it vanish from the render tree the protected
dismiss-guard test locates via find.text), a SEPARATE small Text is
added alongside it. The original label stays a single, untouched Text
node, still inside the same FilledButton the guard taps.
Verified against the full ringing-screen test surface (34 tests
across 5 files, including the protected dismiss-guard file) -- all
green, dismiss-guard file reconfirmed byte-identical to main.
